The equation is .

Compare the equation with .

a = , b = and c = 2

a) Now we can find discriminant value

        (Substitute a = , b = and c = 2)

Product of two same sings is positive.

= 49                                              (Simplify)

b) The discriminant is positive, so the equation have two rational roots.

c) Apply quadratic formula:

        (Replace , a with , and b with )

Product of two same sings is positive.

                ()

The solutions are

The discriminant value is 49 and the equation have two rational roots.

The solutions are .
